摘要

距骨頭與跟骨前三分之一部位相關節的關節面有個別差異，可區分為四種類型：類型I，單一關節面，從載距突上面延伸至跟骨前端內側；類型II，兩個關節面，一個在載距突上，另一個在跟骨前端內側；類型III，單一關節面，局限在載距突上，不向前延伸；類型IV，單一關節面，從載距突上面向前延伸至跟骨前端內側，也向後延伸與跟骨中間部位的距骨後關節面相接合。研究國人289個跟骨中，屬類型I的最多（佔57%），類型II次之（佔42%），類型III極少（佔1%），類型IV則沒有發現。左右腳大多數具對稱性，跟骨跟距關節面類型相同的佔88%。女性跟骨中，類型I所佔比例顯著地較類型II高。

並列摘要

There are individual variations in the talar articular facets on various calcaneus. The facets for the head of the talus can be divided into four types. Type 1 calcanei have one continuous facet on the sustentaculum tali extending on the antero-medial corner of the distal part of the calcaneus. Type 2 calcanei have two articular facets, one on the sustentaculum tali, and another on distal part of the calcaneus. Type 3 calcanei have a single well defined facet on the sustentaculum tali. Type 4 calcanei have a single facet on the sustentaculum tali extending on to the antero-medial corner of the distal part of the calcaneus, but this facet is continuous with the posterior talar articular facet of the calcaneus. The 289 cases of normal Chinese calcanei were investigated, 57% of them belongs to Type 1, next comes Type 2 which embraces 42%, Type 3 contains only 1%, but nothing has been found in Type 4 so far. The right and left calcanei are mostly symmetrical (88%). The incidence of Type 1 in females is significantly higher than those as mentions in Type 2.
